I have been living in seperate bedroom from ex for 3 years kids are now 3 & 4. What affects could you see this is doing to kids. I believe that they will think this is how most people live or later that they should do the same. i want out but ex will not leave. He is a very eggressive, controlling person and more so if he does not get his way. He beleives that staying in the same house as the kids will not effect them. He is not controlling yet to the kids.
